Difficult for the public acceptance of LED lights native worrying development

Recently, Foshan City, Guangdong Province as an energy-saving lamps and LED lighting project pilot area, has completed the Wu King Road, Lu Jing Road, Holland Park Road, Choi Hung Road, Foshan Zhangcha Tunnel Road, Mandarin Way, Tongji East , Fenjiang South Road, South Boulevard (low light), deep-Ning Road, Wufeng Quad, East Ping Lu, Weiguo Road and other sections of lights from job to job. However, LED lights near the public is not very satisfactory, there are people to reflect, to install LED street light, the road becomes dim, there is a big security risk.

On public questions, to respond to the Public Utilities Board Chancheng: LED white light emitted close to the sun, high CRI, high pressure sodium lighting effects better than that. For users reflect the "white is too pale, vilify the city," he thought, this is only because people are used to high pressure sodium lamp of yellow lead.

White alone, a complex light, usually from the wavelength of light, or a mixture of the three wavelengths of light. Currently, LED white way to achieve the main three kinds: first, through red, green and blue color combination of synthetic multi-chip white light; second is the use of blue LED chips excited yellow phosphor, issued by the LED blue and yellow phosphor green synthesis of white light to improve the color rendering properties can also be adding an appropriate amount of red, green phosphor; third, with UV LED (UVLED) stimulate synthesis of three-color phosphor white light. For a long time, China's city lights to the main high-pressure sodium lamp, the public generally adapted to the yellow street lighting, white LED lights also need to accept certain period of time.

Recently, the State Development and Reform Commission and other six ministries jointly issued the "views of the semiconductor lighting energy industry," that will focus on the ordinary indoor lighting, car parks, tunnels, roads, lighting and medical, agricultural and other special areas of development and promotion of LED lighting products, and improve relevant service system.

In 2009, the State vigorously promoting the "10 City 10 000" construction project, planned by 2010, 10-20 cities in the promotion of more than 300,000 municipal LED lighting. This energy-saving environmental protection, stimulate domestic demand, the development of local economy has an important role in many areas, however, the current situation, LED spread of localization, there are still considerable difficulties.

First, the current LED lighting products, prices are still high, although the products in the long term with energy-saving features, but most of their consumers and business users are still on the fence. LED stage lighting products are mainly used for high-grade office room lighting, automotive lighting, government procurement and other high-end applications, development trend of the civilian population slowly.

Secondly, LED lighting patent upstream and downstream products is still in the hands of foreign leaders, local businesses, backward technology, product quality uneven. The main control on the domestic market, OSRAM, Philips and other foreign brands in the hands, these large effect on the local enterprises to build "patent encirclement", making very slow development of local LED company.

Although the domestic market looks promising LED 100 000 000 000 However, local development is still difficult, public acceptability, price and technical factors are blocking the front wall of LED manufacturers. LED in China's development also need the Government's strong support and constant media publicity, have the two together with the enterprise's own self-innovation, believe that the Chinese LED industry will soon enter the world peak.
